Abstract :
A continuous time integrator based on both current and voltage mode processing is presented for applications over the video frequency range. Using a very low-cost 2.4 μm CMOS process, the integrator consumes less than 2.5 mW from a ±1.5 V supply. Experimental results show a tunable unity-gain range from 4.5 to 12 MHz with a 58 dB dynamic range
